Given numbers are 850, 438, 780, 158

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(850, 438) = 186150

GCD(850, 438) = ( 850 x 438 ) / 186150

= 850 / 438

= 850

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 158) = 158

GCD(2, 158) = ( 2 x 158 ) / 158

= 2 / 158

= 2

So, Greatest Common Divisor of 850, 438, 780, 158 is 2
